This is from Nexus and Steam so take it with a pinch of salt.

From what I can gather Mod Fixer is no longer required but some mods require updating with ImprovedUI being mentioned in this regard but this mod was updated at about 2230hrs (BST) last night.

The Mod Fixer description page still has the same comments but the Community Manager from earlier in the week.

I've not installed Patch 2 yet but I might give it a go shortly or I may wait until more of my mods get updated.
